JOSEPH BELFIELD, OF LINCOLN, RHODE ISLAND.

TWlSTER-RING.

SPECIFICATION forming part of Letters Patent No. 422,699, dated March 4,1890. Application filed November 12, 1889| $erial No. 330,095. (Nomodeh) i such rings as are used in the process of Wet twisting, whereinthe yarn passes through water 011 its way to the twister-spindle. Thiswater is immediately thrown off by the yarn in twisting, wetting therails and rings and causing the latter (which are now made of hardenedsteel) to rust and become rough on the outer surface, which is not keptbright by the friction of the traveler. This roughness of the ringcauses the traveler to start hard and frequently prevents it fromstarting, in which case the yarn is broken, and one loose end (as iswell known) often causes the breaking of one orlmore others on eitherside of it, thus necessitating knots in the yarn, waste of stock, andloss of time.

I have indicated above one of the difficulties experienced in the use ofthe reversible steel twister=ring as now made, which it is the object ofmy invention to overcome. I attain that object in the manner shown inthe accompanying drawings, in which Figure 1 is an end elevation of therail, showing ring-plate, ring, and bobbin, with a portion broken awayto show a section of the ring. Fig. 2 is a plan of the ring andringplate. Fig. 3 is an enlarged section of the ring, showing travelerin position.

Similar figures referto similar parts througlv out the several views.

The rail 1 carries the ring-plate 2, into which the jacketed ring 3 isforced. This jacket consists of a thin tight-fitting ring-4, of brass orother restless metal, made nearly as Wide as the inner ring, Which itincloses, and Which serves to protect from rust that part of the innerring not touched by the traveler when in operation.

The ring 3 maybe made with the outer line of its cross-section straight,as at present, or it may be made with a shoulder of about'the depth ofthe thickness of the jacket. This shoulder will hold the jacket in placewhile the ring is forced into the ring-plate 2.

The traveler in operation is in contact with the two edges and innersurface of the hard ened ring 3,Which are thus kept bright; and myimprovement serves to protect the outer surface of the ring 3 from rustand thus greatly increase the life of the ring, besides preventing knotsin the yarn, waste of stock, and loss of time, as already explained.

I claim, therefore, as my invention and desire to secure by LettersPatent The combination, in a twisterring, of a ring of hardened steel oriron with a jacketing ring of brass or other rustless metal, sub

stantially as described, and for the purpose 'set forth.

JOSEPH BELFIELD.
